Be it known that I, Fnnnnnioir GORE, a citizenof theUnited States, residing in Somerville, in the county of Middlesex and State of Massachusetts, have invented an Improvement in Self-StartingAppara drawings representing like parts. 0 I This invention relates to an" apparatus,

which is especially adaptediamongi other T 5 J bafck plate 12- and. into aichamber 20 a formed by a llanged plate or diskQl, which is see, cured to the b ack plate fluid-tightgby screws 22 or otherwise; The crank shaft 6 within theZchamber-QO;has/fast on it a pinion23, which;meshes with preferably two gears 124g mounted on stud shafts 25, carriedbythe uses, to be employed as aself starter'for'the engine or motor of automobiles and' thejliker The invention has for itsiobje'cttopro-vide a simple, inexpensive andiefiicrent apparatus,

which can be readily applied to automobiles. now in use, and which hasj provision for en abling the apparatusto be used as a; drivmg" member for the internal-combustion "engine of the automobile or other vehicle, and'whlch also has provision for enabling the engineer i motor to drive the apparatus. To this end I employ a clutchimember which is capable 5 V .d1sk' 28' having a hub or annularfiange 29 of bein attachedto or connected with the shaft 0 the engine or motor, and a second clutch member which cooperates witlrthe first mentioned clutch member and is geared to a, rotatable shaft, so that'rotation ofthe latter eflects rotation. of .the' engine shaft through the caring and clutch members re-- ferred to. rovision .lis also' made for cou-. pling the rotatable shaft'directly to the en's gine shaft, so that the latter can drivethe former when desired.

Provision is made for rotating the. rotae table shaft by one or 'more iluid operatedm tors. L vention will be pointed out in the the end of this 'specifi'cationg Figure. 1 is. a vertical sect on andfel'eVa claim at tion of one fonn ofapparatus embodying i this invention. i o

e and bygmeans of the rollers81 is coupled to' theclutch member 30, 29,which is connected rgby'gearin'g with the crank shaft. of the air I l pump, so that, when the crank shaft of the 'pumpisarotated by air pressure, aswill be I Provislicnwis also made for coupling the' crank shaft 6 of the air pump directly to the shaft of the engine or motor, when it 1s desired to have the engine or motor drive the air pump as will be described.

To this end, the clutch'member 34, 35,

g which is connected with th engine or motor, has located within it an expanslble and contractible ring 40, which'is external to a segwhich cotiperates with a like groove 50 on a lever 51 for the-reception of a pin 52, the lever 51 being provided with an arm 53, which extendsove'r one end of the flange 41.

The levers 48-, 51 are thus suspended from the flange 41 and the ring 40, and'are ca- Y pable of having their lowerends separated by a cone 55, which coiiperates with in clined walls 56 on the levers, said walls forming a V-shaped opening, see Fig. 3', into which the apex of the cone-55 enters. The cone 55 serves to spread the lower ends of the levers apart, and thereby causesthe 1e ver 48 to move thefree end of the eXpansible ring 40, and cause it to expand and fric- V the crank shaft of tionally engage the clutch'member 34, and

thereby couple the latter to the flange41,

which latter'is attached to the crank shaft (3 of the pump, and as a result the shaft 6 is directly connected with the engine shaft and is driven at the speed of the engine shaft. It will thus be seen that in the present instance, the clutch member 34, which is connected with the shaft of the engine, 00- operates with two separate clutch members, one of which to wit, the member 30, 29, is indirectly connected with-the crank shaft of the air pump, and the other of which, towit, the member 40, is directly connected with the air pump through the flange 41. w l 5 g 7 "Provision is made for controlling the admission of air under pressure from a suitable source of supply into the cylinders of I the air pumps, when the latter are used .for

7 starting the rotation of the engine shaft,

and also for. replenishing the pressure supply by the air pumps. j 1

have represented one arrangement of apparatus for this purpose.

To this end, the crank shaftie of the air pumps has fast on it an eccentric disk-60,

which operatesa valve for each air pump. .The valve, referredtols shown as a cylmdricalrbd 61, see Fig. '1, whichis movable in a bore in the web 62 attached-to each cylinder a, and is arranged to cover and unsage .76 indicated by cover the end of a passage 63, which con:- inunicates with the crank case 10. The valve 61 has its outer end engaged by a lever 64, see Fig. 2, which in turn engages the periphery of the eccentric 60, so that, in the rotation of the eccentric, the latter acts on the lever 64 to move the valve so as to close the inner end of the passage 63, and then to permit a spring 65 to move the valve outward and open the inner end of the said passage. The bore in the casting or web 62 in which the valve 61 moves, is enlarged at its outer end to form a valve seat 66 for a check valve 67, which is seated by a spring 68 and is opened by the valve 61, which latter abuts against a stem or rod 69 on the check valve 66. In the present instance, the valve rod 69 is extended into a socket or hole in the end of the valve 61, and said socket is made of sufficiently shallow depth, to insure the bottom of the socket engaging the stem or rod 69, after the valve 61 has been moved into position to close the inner end of the passage 63 and before the high part of the eccentric 60 engages the lever 64, so that, when the high part of the eccentric engages the lever, the valve will benioved suliiciently far to force the check valve 67 off of its seat and open the check valve, and therebv establish connnuication between a chamber 70 between the two valves 61, (37 with a port 71 in the back plate 12, which port communicates with the annular groove or chamber 72 in the rim of the plate 21, which groove is connected by a pipe 73 with a tank or vessel 74, which constitutes the supply tank for the fluid under pressure and is shown in Fig. 1 on a small scale. The pipe 73 is provided with a suitable valve 75 controlling the passage of air into and out of the supply tank, and designed in practice to be actuated by the operator of the automobile or other vehicle.

The chamber 70 is connected by a pasdotted lines in Fig. 1. with the outer end of the pump cylinder (1.

' The eccentric disk 60 may be fastened to the crank shaft by screws 78 or in any other suitable manner.

The piston rods 6 of the pumps may be secured to the crank pin (Z in any suitable manner, and in the present instance each piston rod is provided on its inner end with a circular flange 80 over which it fitted a ring 81, which couples opposing piston rods to the crank pin.

The eccentric 60 is so shaped, that no matter where the crank shaft e of the pump stops, one at least of the valves 61 is in contact with the stem or red 69 of one of the check valves, and the latter is opened to connect the chamber 70'with the supply tank, and through the passage 76 with the cylinder a. As a result, when the operator desires to start the engme, he opens the tank and receives fluid pressure therefrom.

valve 75 and allows air or other fluid'und'er pressure, say of '80 lbs; toe'nter one ofithie air cylinders 11, and c this air pressure" acting against the piston in said cylinder-starts. the crank shaft in rotation, and each-Ppump in succession is connected with th'e supply The crank shaft 6 of the air'pumps'is thus rotated in the direction contra to the movej ment of the hands of a watch, and through the pinion 23 andgears 24 rotates the. in ternal gear 26 in the direction of the hands of a watch, thereby rotating the'clutchmeiir' ber 29, 30 in this direction. The clutch member '29, 30 in its rotation inthe direction indicated by the arrow 85 in Fig; 3, whichgis shown as contrawise ofthe clock because of the section, on which Fig. 3 1s taken, moves the steel rollers 31 from the wide part of the through the gearing referred to. The engine j or motor is thus started in operatlon, and

when running properly, theop'erator'closes the valve 7 5 and the air -pumpscease to op crate, and the crank shaft 6 and the clutch member 30, 29 come to rest, as the clutch member .34, which rotates withthe'f engine shaft advances sufficiently to bring the wide parts of the recesses 32 toward the rollers31 and thereby unclutches the member[ 30, '29, from the rotating member 34, which allows the former and the crank shaft of the air pumps to come to rest. If the operator desires to replenish the air pressure in the Supply tank 74, he moves the cone forward into engagement with the inclined surfaces 56 of the levers and separates the lower ends of the same, and causes the ring or clutch member 40 to be expanded into frictional'engagement with the clutch member 34:, thereby directly coupling the engine shaft with the crank shaft of the air pumps, so that the crank shaft is driven at the same speed as the engine shaft. As a result, the air pumps quicklyrestore the air pressure in the'supp1y1 tank.

engine shaft, the piston of each cylinder sucks in atmospheric air into the crank case through a port 88, see Fig. 1, and from the crankcase through the passage 63, chamber 3 7 0 and passage 76 into the cylinder a,'on one stroke, and on the return stroke discharges it through the passage 76 into thes chamb'er and from the latter -through the'portlhy annular groove 72 and pipe? 3 into the tank 74, the valve 61 being at. suchtime closed I and the check valve6Z being open.

The cone '55may be moved by theopera-p tor, through a suitable lever, not shown, but 1 which engages the socketed ends of a barfor shaiany part of the apparatus. The frictional engagement of the clutchmembers 34, 30 I through the rollers 31 is morepositive without 'theair wise driven; v
